Research on Multi-Level Indicator of Hoist with PROFIBUS-DP Interface
Traditional elevator indicators have been improved for traditional elevator indicators with strict communication requirements, high communication costs, and unsuitable for fieldbus-guided industrial production. That is, the PROFIBUS-DP interface is developed for the traditional hoist multi-level indicator, and the bus bridge is used to complete the communication protocol conversion during the data transmission process, so that it can be added to the field bus production system. This paper deals with the design of the multi-level indicator hardware circuit of the hoist with PROFIBUS-DP interface and the design of the software circuit. Finally, the system test platform was built to verify that the hoist indicator structure is simple and reliable.
